Foursquare: Split the App in Two?

It's early 2014. You are a PM at Foursquare, one of the most beloved mobile apps in the world. You have built an incredible check-in network driven by a strong social graph and addictive gamification (competing for Mayorships, unlocking badges).

But you have a strategic dilemma. The data shows your user base is split. Half your users open the app purely as a social radar ("where are my friends right now?"). The other half use it as a local search engine ("what's the best pizza nearby?"), directly competing with Yelp and Google Maps.

The app is getting bloated, trying to serve both masters. The UI is confusing. The leadership team is looking at Facebook's successful unbundling of Messenger and considering a radical move: splitting Foursquare into two separate apps.

The plan: The main 'Foursquare' app will be entirely redesigned for local search and reviews, stripping out all check-ins. A brand new app called 'Swarm' will be launched exclusively for social check-ins and gamification.

This is a Tier 1 League Match. The decisions are binary and the consequences are terminal.

The principle: Splitting a single app into two to serve divergent use cases breaks the core habit loop that built the network. When utility is powered by gamified social interactions, unbundling them destroys the data flywheel that makes the utility possible.
